Saturday February 15 from 10 am to 5 pm: Stop by today and see what we’ve done! Drywall is up and mudding the seams is “in process”. Over the next few months, finishes—from paint to cabinets to counters—will be installed, all vetted for their ultra-low or non-toxic properties. Ask me anything you want about the construction so far—like how to source healthy materials, what makes it super-insulated, what makes it low-carbon footprint, and what makes it zero net-energy.
A beautiful, sparkly snow fell on Sunday. It shut down solar production for the day and the next and the next. That’s the downside of a roof-mount install. A ground-mount (on a rack) could be swept clean. My low pitch roof (3:12) doesn’t help. Snow would slide off a steeper roof faster.
How do I know when the PV (photovoltaic) system is working? The easiest way is to look at the meter on the side of the garage. If the arrow is pointing toward the street, I’m sending kWh’s to the grid, and getting paid. If the arrow is pointing toward the house, I’m buying from the utility. Of course, it constantly varies depending on sun and clouds and whatever equipment I might be running. I’m paid 3 cents/kWh for my production. When I buy, it’s at 12 cents/kWh.
There’s also an app for that. I can look at my phone to find out exactly how much the panels are producing, hour by hour. Last week a clear day with no snow netted me 31 kWh of electricity. That’s equivalent to running an efficient refrigerator for 19 days. It’s also equivalent to the greenhouse gas emissions of driving a car 53 miles.
